EYEGLASSES.

SPECIFICATION forming part of Letters Patent No. 507,434, dated October24, 1893.

Application filed April 3, 1891- Serial No. 387,569. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES M. HAYNES, residing at Chillicothe, countyof Ross, and State of Ohio, have invented new and useful Improvements inEyeglasses, of which the following is a specification.

The objects of my invention are first, to provide a means of adjustingthe distance between the centers of the lenses to the pupillarydistance; second, to provide a means for adjusting the distance betweenthe springs holding the nose pieces to the width of the nose, and thiswithout interfering with the adjustment of the centers of the lenses tothe pupillary distance; third, to provide a self adjusting nose piece. Iattain these objects by the devices illustrated in the accompanyingdrawings, in which Figure 1 is afront viewof the entireframe; Fig.2 aside View of the entire frame; Fig. 3 an enlarged view of the right halfof the frame. Fig. 4 is a side view of the spring and nose piece, andalso a vertical section through the center of the clamp for holding theadjustable bar and spring.

Similarletters referto similar partsthroughout the views.

B is a rigid bar. l

C and T are the respective parts of a clamp.

C is a band so shaped as to make an orifice of such size and form as toadmit the easy passage through it of the bar B, the spring S, and theprojection L, and provided with a threaded hole on the under side.

T is a setscrew passing through the th readed hole in the under side ofband C.

S is a spring, as above stated, the upper end of which passes throughthe clamp C T. By means of the clamps O Tand OT andbar B, the positionof the lens rims R and B may be so shifted as to bring the centers ofthe lenses directly before the pupils of the eyes, and by changing theposition of the upper end and horizontal part of the spring S, thedistance between the springs S and S may be adjusted so as toaccommodate the width of the nose. The spring S at a point about onehalfto three-fourths of an inch fromits upper end is bent downward in analmost vertical direction,'as shown in Figs. 1 and 3. To the lower endof said spring S is attached a wire projection O bent downwardly andinwardly as shown in Fig. 4, at the end of which the nose piece N ispivoted at such an angle as to be almost, if not quite, parallel to theupper line of the nose of the wearer. The nose piece N is pivoted on itsupper side at a point about one third the distance of its whole lengthfrom its upper end to the wire projection 0, thus assuring the nosepieces N and N such a position as to be most easily placed upon thenose.

L is a projection fastened to the rim R of such shape and proportion asshown in the figure. Its upper surface where it passes through the clampO T is plane and on its under side is a depression D into which the setscrew T fits. Thus the rim R is kept in its position when the set screwT is slightly loosened to adjust the bar B or the spring S.

I claim 1. In an eye-glass frame, the combination of the single bar B,the rims R adjustably secured to the bar B by means of the clamps O, thesprings S, adjustable relatively to the bar B and provided with theprojections O bent inwardly and downwardly, and the yielding nose-piecesN on the said projections, substantially as shown and described.

2. In an eye glass fra me, the combination of the bar B, the rims Rprovided with the projections L, and the nose piece springs S, withsuitable clamps such as C embracing the bar B, projections L and springsS for securing the parts together, whereby one part may be independentlyadjusted with relation to the others, as set forth.
